I am pleased to announce the field test of Caché and Ensemble 2017.1, including many new improvements.

The product team at InterSystems looks forward to your participation in the field test and feedback over the coming months.

Some of the more significant changes in 2017.1 are the new RESTful APIs for iKnow, FIPS 140-2 validated cryptography for Caché database encryption, and improved DocBook search.  As always there are a host of scalability and performance improvements to the core database and SQL.  And hundreds of smaller improvements and corrections.

I have a soap webservice extended from  %SOAP.WebService class

Lets say i have web method and have return type of following classes (either one of them)

Class ReturnTypeA

{

  Property SelectedDoses As %XML.DataSet;

}

Class ReturnTypeB

{

  Property SelectedDoses As list Of WebServices.DataTypes.Dose;

}

Which return type class has better performance while in terms of xmL serialization ? A or B

my client application is in C#

looking for what the timeout value is for the connection for shadowing. and if it is known the timeout for mirroring also.

I'm currently getting this error and when we go to mirroring it would be good to know also, this way we can go back to our network vendor and give them as much info as possible.

10/19/16-12:19:40:696 (d30b6) 2 [SHADOWING] SHADOW SERVER (PRODSHAD): <ZREAD>ReadNone+3^SHDWUTIL;ERROR #1071: TCP read timed out - remote server is not responding (repeated 16 times)

The technology of load balancing between several servers with relatively low capacity has been a standard feature of Caché for quite a while. It is based on the distributed cache technology called ECP (Enterprise Cache Protocol). ECP provides a host of possibilities for horizontal scaling of an application, and yet keeping the project budget fairly low. Another apparent advantage of ECP network is the possibility to conceal its architecture in the depths of Caché configuration so that applications developed for the traditional (vertical) architecture can be fairly easily migrated to a horizontal ECP environment. The ease of this process is so mesmerizing, that you start wishing it was always this way. For instance, everybody is used to having a possibility to control Caché processes: the $Job system variable and associated classes/functions work magic in skilful hands. Stop, but now processes can end up being on different Caché servers…

This article is about how to gain as much transparency in controlling processes in ECP environment as in traditional (non ECP) one.

In DeepSee we have a field that is numeric but is used as a dimension. In DeepSee it sorts this field in the following order. 10, 11, 15, 2, 3, 5, 6, 8, 990. Is there a way to have DeepSee sort it numerically instead of treating it like a character field? We would want to see it show up in the dimension as 2,3,5,6,7,10,11,15,990.

Hi,

I try to programmatically create a parameter for a dataCombo ZEN Component (which is in turn created on the server side at runtime).

Set tParm = ##class(%ZEN.Auxiliary.parameter).%New()
Set tParm.id = "pRegion#"_pExamContainerCount, tParm.name = "pRegion#"_pExamContainerCount

Set tExam = ##class(%ZEN.Component.dataCombo).%New()
Set tExam.id = "Exam#"_pExamContainerCount, tExam.label = "Untersuchung", tExam.queryClass = "Inventory.ServiceCatalog", tExam.queryName = "QGetExaminations", tExam.showEmpty = "false", tExam.size = "52", tExam.onchange = "zenPage.updateExamDescription(zenThis.

Hi

I'm trying to use the ##class(%File).RemoveDirectory utility to delete a windows folder. The folder has nothing in it, but it is not getting deleted.

I've tried doing Set sc=##class(%File).RemoveDirectory(file,.return) and return is returning a -2.  I've also tried changing it to .Delete in case that worked, but I got the same. 

I've tried it on my local instance and on a customer site on an older version of Cache that doesn't have the return parameter, but it also fails to delete the folder on there too.

file is the full filename and path and the .Delete works fine when used on files.

Since now i have been working from external connection but i want to work with the SQL utility of Management Portal

i dont know how to do with several instructions like in other editors like this example

update Prod.Articulos set Alto = 1646, Ancho = 16, Fondo =  80 where CodigoNum = '100' and Empresa = 'CO'
update Prod.Articulos set Alto = 1646, Ancho = 16, Fondo =  400 where CodigoNum = '101' and Empresa = 'CO'
update Prod.

Hi,

How to change READ ONLY Database to READ/WRITE Could not find an option to edit it.

Thanks, Sansa.S

Can Cache Monitor (^MONMGR) and System Monitor be configured to also send 'OK' messages? With the first bad email, you still wonder if things are still broken, when in-fact normalcy has been restored, some even within some seconds.

Many of us installed Ensemble a few years ago, estimated space to be sufficient and now run into surprise - hard drives are getting full! 

Hi,

I have a process that is importing lots of data from an external file, but every now and then I come across a STORE error.

I know that the STORE error is occurring in the %Save method of the class but I know very little else and I think its something to do with a lage amounts of Related Objects.

Is there a method of finding out more information regarding this error i.e. which actual object was being saved etc etc.

Thanks

Jim

Hi All,

I have SourceControl utility class as in sys namespace

 Class %MW.Web Extends %CSP.Page {... }

Previously with Cache 2010.1 and below  there was no problem accessing it through

localhost:57772:/csp/myns/%MW.Web.cls

But now with newer version at least with  2016.2  I' ll get Forbidden message from it.

With Web Gateway HTTP Trace Facility 

GET /csp/ipanax2/%MW.Web.cls HTTP/1.1  

​-->  HTTP/1.1 403 Forbidden  

How can we make it accessible again?

Hi All,Can you please any one tell me how to find the last compilation date of routine.

Running TuneTable accounts among other the parameter named Block Count. In documentation, we see that this is an approximate numbers of 2K-blocks in which SQL-maps are stored. Databases in recent Cache doesn't support 2K-physical blocks so SQL-blocks are not physical blocks as it seems. So two questions:

- what are these blocks?

- how knowledge about count of blocks can help in SQL optimization?

Thanks for intelligent answer to stupid questions!

My SOAP Operation is returning an error "ERROR ErrBusinessDispatchNameNotRegistered: Business dispatch name 'PKB_SOAP_Sender' is not registered to run"

How to I resolve this?

The DeepSee TroubleShooting Guide helps you track down and fix problems occurring in your DeepSee project. A common problem is finding less records than expected in a DeepSee Cube or a related Subject Area. The DeepSee TroubleShooting Guide suggests starting your investigation by checking the following:

Check cube for build restrictions

Check if maxFacts is used

Check if Build Errors are occurring

A new Health Connect customer has a few experienced Java folks on their interface team. As they get more into Health Connect and learn Caché ObjectScript they thought it would be useful to have a list of common Java statements with an equivalent statement in ObjectScript. They mentioned string manipulation as an example, but would be interested in other areas as well.
 
This seems like something that is probably already floating around somewhere. Does anyone have something like this or other "COS jumpstart for Java devs" materials?
Thanks,
Marc

Question:

Where can I find the openssl command line tool for Windows?

Answer:

The openssl command line utility comes with Unix, but not with Windows. It is used for working with security certificates.

The main site is

https://www.openssl.org/

There are no binaries on this site but in the Community section there is a link for binaries which leads to:

https://www.openssl.org/community/binaries.html

This contains a link to "An informal list of third party engines":

https://wiki.openssl.org/index.php/Binaries

At the time of writing this had two entries for OpenSSL for Windows.

I'm working on a REST service which will include a binary stream as a request property. I'm currently encoding the stream as BASE64 and passing it as a string value, but I was wondering if there is anything in the Caché JSON support that may be a better fit for encoding this data? Thanks Chris

Lets say i have a record "Person". If i want to access the "Name" property of that object which one of the following best option performance wise

1. Option 1

set record = ##class(Test.Person).%OpenId(1)

write record.Name

2. Option 2

 write ##class(Test.Person).NameGetStored(1)

Microsoft Office has components for using in third party applications: COM Objects for C++ and Interop Assemblies for .Net programming.

Many Cache projects used to include calls to those libraries. However, recently this solution started being problematic.

There are two main reasons - legal and technical. Let’s check the details.

Microsoft technology support

Microsoft is supporting Office Automation only for desktop computing. 

It shall not be used for server computing, as they offer Sharepoint for this scenario.

Recently I wrote about automatic removal of system methods from the codebase.

Today, I'm ready to present you a working solution (codename: SMR) for this task.

Hi all,

We've found that in most cases when we open a new CSP session the CGI varaiable %CGIEVAR("HTTP_COOKIE") contains the client name.

It looks like that : "state=SYSADM%3A0; Username=Urish; CSPWSERVERID=Cache for Windows (x86-64) 2013.1.1 (Build 501_1_13062) Sun Aug 11..."
In some other cases this CGI only contains  $zv - like "CSPWSERVERID=Cache for Windows (x86-64) 2013.1.1 (Build 501_1_13062) Sun Aug 11 2013 23:20:33 EDT"

We are searching for a way to get the username (we need to stop using activex controls, like WScript.Network-->

This is a list of all the posts in the Data Platforms’ capacity planning and performance series in order. Also a general list of my other posts. I will update as new posts in the series are added.

You will notice that I wrote some posts before IRIS was released and refer to Caché. I will revisit the posts over time, but in the meantime, Generally, the advice for configuration is the same for Caché and IRIS. Some command names may have changed; the most obvious example is that anywhere you see the ^pButtons command, you can replace it with ^SystemPerformance.

We are trying to understand how websocket connections from a javascript client may timeout in cache. Does anyone know if and of the session timeout or any other timeouts apply to any synchronous websocket connections? I have not been able to prove that they do timeout at all.

Hi,

I have a requirement to convert uname -n (Unix comamnd) with its equivalent Cache class. Can anyone help on this please

I tried using the DeepSee Troubleshooting guide but the suggestions weren't working.  Let's say that the source data we are using to build the cube on has a value out of range. This would cause the cube build/update to fail. How do I see the error log that explains which field has the value out of range? Please be detailed on exactly what command I should enter and where I should enter it in.

I assume that I go into a terminal session and to the correct namespace that we are building/updating the cube on, but the DeepSee Troubleshooting guide doesn't give that detail.

This article explains the basics of OpenVMS file structures, from a Caché prospective, and what you need to know to read and write any OpenVMS file with Caché, even the files with difficult file structures.

On UNIX and Windows all files are just a stream of octets (eight-bit bytes). Assigning meaning to those octets is done entirely by convention. Those conventions are rather simple, even if slightly different on UNIX and Windows.
